推荐答案

以下是一些bash脚本和一个名为timelimit的程序，可以解决您的问题. 被允许运行一段时间后杀死进程时间

Here are some bash scripts and a program called timelimit which may solve your problem. Kill process after it's been allowed to run for some time

我想我找到了一个更好的解决方案.尝试使用超时程序.从手册页: 超时-运行具有时间限制的命令".例如:

I think I found a better solution. Try using the timeout program. From the man page: "timeout - run a command with a time limit". For example:

timeout 5s sleep 10s

它基本上运行您的命令，并在指定的持续时间后将其杀死.

It basically runs your command and after the specified duration it will kill it.
